This invention relates to coil mountings, and is more particularlydirected to such type of mountings that are commonly employed in radiosignalling for supporting or hav-` ing mounted thereon inductance coils.

The object of the invention is to provide a mounting of this characterwhich is simple in structure, eflicient in operation, and economical ofmanufacture.

A further object of the invention is to provide a mounting of this typewherein maximum efiiciency and Variation in coupling between inductancecoils may be secured. a

A further object of the invention is to provide in a mounting of thistype means whereby any type of inductance coils may be most eflicientlypositioned With reference -to each other, and wherein the most eiiicientcoupling between the circuits in which the coils are included may beeiected.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the Construction, combination,location, and relative arrangement of parts, all as will be more fullyhereinafter set forth, as shown in the accompanying drawing, and finallypointed out in the appended claims.

Referring to the drawing y Fig. 1 is a plan view o' one type of coil`mounting embodying my invention.

Fig. 2 is a sectional View taken on the line 2, 2, Fig. 1, looking inthe direction of the arrows.

Fig. 3 is a sectional View taken on the line 3, 3, Fig. 2, looking inthe direction of the arrows.

The same part is designated by the same reference numeral wherever itoccurs throughout the several views.

WVhere a loose coupling is desired between the inductance coils, andespecially in the radio art, it is customary to vary the position of thecoils relative to eac other by hand, moving one coil relative to theother, and rely on the weight of the coils to prevent further movement.This movement is unsatisfactory in that a jar to the panel supportingcoils, or the table on which the coils are laid, frequently cause theadjustment thereof to become disturbed. Further, a fine adjustment orspace between the inductance coils frequently required, especially inradio work, is difficult to obtain in this manner. WVith the advent ofthe type of coils known as honeycomb coils, duo-lateral coils, spiderweb coils, or the like, held by a mounting, it became the practice toemploy in connection with these coils a standard type of mountingwherein one coil, usually the center coil, was held rigidly by themounting or support, and the other coil or coils, if more than two coilswere employed, were supported by the mounting for pivotal movementrelative to the fixed coil. I have found that the most efficient resultsare obtained when the fixed coil can be moved vertically or laterally,as the case may be, relative to the pivotal coils. In other words, forexample, in the case ot' a three coil mounting, where 'the center coilis fixed and the two side coils are pivotally supported, when the properpivoted position of the pivotally supported coils is eiected, greatadvantage is obtained in being able to move the fixed coil, that is,fixed so far as pivotal movement is concerned, relative to the pivotedcoils in a straight line or plane as distinguished from pivotalmovement. structure which secures the advantages of such an arrangementand is capable of the foregoing operation. I have shown, and willdescribe the structure as a triple coil mounting, but I wish it tobeunderstood that I do not desire to be limited or restricted in thisrespect, as two or more coils may be employed and embody the features ofmy invention. F urthermore, I have shown for the purpose ofillustration, a honeycomb or duoateral type of coil, but I do not desireto be limited or restricted in this respect, for any type of inductancecoil commonly enployed in the radio art, such as either of the twomentioned, or the so-callcd spider web coil, etc., may be employed.

Referring to the drawing: I have shown a coil mounting structure adaptedfor connection to a vertical type of panel board. Obviously I do notdesire to be limited to any particular type as by mere matter of designthe structure may be supported b a standard or adapted to be connectedto the horizontal type of panel. The support consists of the back 1. Theback or base 1 has Secured thei-eto two frane members 2 and 3, spacedfrom each other. The frame members 2 and 3 *form a support for shafts 4and 5, which, in turn, support socket blocks 7 and 6. These blockscontain plug and jack arrangements in the form selected for illustrationfor attachment to similar plug I will now describe a and jack blOClScarried by the inductance coils in the manner now well known in the art,:tor example, as shown in Letters Patent No. 1,365,170, January 11,1921, to R. F. Gowen. The inductance coil is illustrated at 8, and theblock thereot at 9. In the manner illustrated in the Gowen patent aboveidentified, the sha'fts e and 5 are each provided with a a e-ar wheel10, generally located underneath the frame 3, which mesh with gearwheels 11, carried by shatts 12, the 'movement ot" 'which is controlledby handles 13. By this arrangement it will readily be seen that byrotating handles 13, sha'fts 4 and 5 may be rotated, and thus pivot-almovement imparted to the respective coils 8. The toregoing structure'forms no part ot' my present intention, and the standard type employedin the art today as illustrated in the Gowen patent above identified hasbeen selected tor the purpose ot illustration ot' the intention hereinvolved. My intention has :tor its object the adjustment of the coil,which hitl erto has been unadj'usta'ble, and the adjust'nent is a linearadjustment rather than a pi'votal one. In accorda'nce with my intentionI doyetail the frames 2 and 3, and provide the usual plug and soeketblock 1%. lilewise do' etailed, to t'orm a dot'etailed slidingconnection in the :frames 2 and 3. A coil S nr y. in a manner similar toblocks 'i', he plugged into the block 14. The block 14.. however, isprovided with gear teeth 15, which are in mesh with a worm 16, carriedby shatt 17, supported by the trame members 2 and 3, which shatt 17 isadapted to be rotated 'by knob 18. From the toregoing it will beapparent that by rotation of the knob 18, the block 14, and inconsequence the coils supported thereby, may be moved, in this instance,Vertically, without yarying the lateral adjustment between the eoils 8.In this manner a most efficient positioning of the intermediate coil, orthe so-called fixed coil` may be secured,

I and the elements of coupling most etticient tor any nrticular Value ordesign ot coil may be thus obtained. lVhile I have shown and describedthe foregoing structure as illustratiye of the invention, I wish it tobe understood that I do not desire to be limited or restricted to thedetails ot structure thereot, as many modifications and changes in thedetails will readily occur to those skilled in the art Without departingfrom the spirit and seope of my invention as detined in the claims.

Having now set torth the object and nature ot' my nvention, however, andhaving shown and 'described one practical structure embodying theprinciples thereot', what I claim as new and useful and ot my owninvention and desire to secure by Letters Patent is,-

1. In an inductance coil n'ounting, the combination with a support, ot'a rotatable member carried by said support, ot a second memberpositioned adjacent said rotatable member, means tor moving said secondmember in a plane parallel to the axis of rotation ot said rotatablemember, means for securing inductance coils to said members to 'formitigid units therewith.

2. In an inductance coil mounting, the combination with a' support, ofan inductance coil pivotally carried by said support, a second coilcarried `by said support, and means for moving said second coil in saidsupport linearly in a plane parallel to the axis of piyotal movement otthe first mentioned coil. e

In an induetance coil mounting, the combination with a support, of aplurality ot' coils carried by said support, neans tor imparting piyotalmovement to said eoils independently ot each other, an associated coilalso carried by said support, and means tor i'mpart-ing line-ar movementto said a sociated coil.

4-. In an inductance coil mounting, the combination with a support, ofan inductance coil piyotally carried by said support, a second coilcarried by said support, and means for moying said second coil in saidsupport linearly in a'plane parallel to the axis of pi otal movement ofthe first mentioned coil, and independent manually `'operated means formoving said first mentioned coil.

In testimony whereof I hare hereunto set my hand on this fifth day ofMay A. D., 1922.
